TLDR Pruthvi faced an error with ClickHouse client. After resizing the disk, deleting a file, and restarting Otel collectors, the issue was resolved.

Where are you seeing this error?
How did you arrive at this state? While you may have seen this error in collector — the real issue is with ClickHouse.
I was seeing this in otel collector.
And I connected to clickhouse pods, then saw a log that no space found. Then I resized the disk, deleted the above file and restarted Otel collectors, then it worked
